After testing around various solutions for a few days I came to decide for ChunkVNC, I simply like the slick and simple way it utilize UltraVNC, so now I'll finally be able to build a remote support solution that even my (often Pc Muffins) customers manage to understand

However, I noticed a "problem" with the Viewer - it doesn't allow me to have a chat and file transfer window open at the same time :=(
I understand the viewer is a component of UltraVNC but searching the full forum I couldn't find anyone complaining about this, which I would expect as I see this as a major limitation.
I tested to replace your 1.0.9.4 files with originals from 1.0.9.6 which basically works, although uvnc viewer complains "The Plugin cannot be loaded. Please check its name integrity." and then connect w/o encryption (any idea about that?).
But it still seam to have the same issue with not allowing the 2 windows to be open at the same time, is this after all a known issue/limitation with the UltraVNC Viewer?
